SIPHON WATER-CLOSET,

SPECIFICATION forming part of Letters Patent No'. 415,128, dated November 12, 1889. l

Application filed November 22, 1888. Serial No. 291,604. (No model.)

To (LZZ whom, it may concern/.-

Be it known that I, WILLIAM SCOTT, of the town of Medford, in the county of Middlesex and State ofl Massachusetts, have invented certain new and useful Improvements in Siphon Water-Closets, of which the following is a full, clear, and exact description.

The improvement of this invention consists, in substance, in the'combination, with a water-closet. bowl having, preferably, a flushingrim, or otherwise suitably adapted to be flushed, and two water-traps with a column of air between and located inthe dischargepassage of the bowl and making a siphon, a single water-supply pipe leading from a tank or other suitable supply, and an opening and closing valve to open and close said waterpipe, of two separate vra/ter ways or passages leading from 'andboth always 'in open communication with said water-pipe and one in communication with the ilushing means of the bowl and the other, of less area than said water-pipe, directly with the air-column between the water-traps, whereby with said valve opened the water from the water-pipe is delivered simultaneously through one of said Water-ways to the flushing means and through the other of said water-ways to the aircolu1nn between the water-traps and with said valve closed substantially only to the ushing means.

In the drawing forming part of this speciication the figure is a central vertical section of the contrivances of this invention, some parts, however, being shown in elevation.

In the drawing, A is a water-closet bowl, which has a flushing-rim B, a water-trap C, a discharge-passage D, leading from said trap C, a water-trap E in said passage D, a column F of air between saidjtraps C E, a waste-pipe G (shown as broken olf) in continuation of the discharge-passage D of the bowl, a watersupply pipe I-I, and a water-tank J, to which said pipe 1I is connected and of which it constitutes the discharge, and has an opening and closing valve K, for opening and closing it, all substantially as well known, except as to the features of this invention hereinafter particularly described. The discharge-passage D of the bowl is the longer leg of a siphon, of which the water-trap C at the bowl is the shorter leg. The discharge-pipe H of the tank connects with a water-way L, which leads and opens to the flushing-rim B of the bowl, and also with a water way or passage M, preferably of less area than the pipe H, that leads and opens to the longer leg of the Siphon-discharge D, and it is shown opening to said discharge D at the upper end of the column F of air between the traps C E. The walls a of this water-Way M, as plainly shown, project beyond the wall L2 of and into and lacross the water-Way L, which leads to the ushing-iim, and thus, as will hereinafter appear, the water-way M is guardedand protected against the entrance of water from the 4supply-pipe H, common to it and the waterway L of the flushing-rim.

Under the arrangement of the water-ways yL M of the bowl, and in communication with each other and with a water-supply pipe, all as has been described, first, with the valve K opened, water is then delivered to both of said water-ways simultaneously, and in part entered through the iushing-rim into the bowl and in part' into the longer leg of the Siphon-discharge, in the first instance flushing the bowl and in the second instance starting siphonic action of the discharge-passage, and thus securing the discharge of the contents of the bowl, and, second, with the valve K closed the water which then flows through the water-supply H being, as well known, of a greatly-reduced volume or body as compared with its volume when the valve is opened, is substantilly all entered into the water-way L and delivered to the flushing-rim to refill the bowl-trap C, the siphonic action of the discharge during the meantime having stopped because of the admission of air to said discharge, for the reason that at all parts of its flow its quantity or volume is not sufficient to fill the water-Way L to an extent such that any will or can enter into the waterway M leading tothe Siphon-discharge.

In order that this afterilow of waterto the bowl to refill its trap may be always sufficient for the purpose, it is preferable to provide a supply of water supplemental, as it were, to the main supply of water, with the valve opened, and a well-known method or means for this purpose is to provide the tank with a IOS water-chamber J 2 at its bottom, in communication by ports b with the disehargepipe ll of the tank, so that when the valve is opened water may be zwcumulated therein for being, when the valve is closed, afterward delivered to the dischargepipe .ll and thence conducted to the bowl, as stated. However, this constitutes no part of this invention, and, again, in lieu thereof, any other ot the well-known ways of supplying a limited quantity of water to the water-supply pipe to be conducted to the bowl after the valve ol' sneh pipe is closed maybe used.

rlhe water-way M, leadiu to the Siphon-dis charge D, preferably, should also serve as a passage :t'or air to pass into said discharge to break its siphonic action, and, as shown, the water-way is so adapted to act.

The bowl for being flushed may be other wise adapted, as well known,than by the way or means-such as a flushing-rim B-herein particularly described-as, tor instantie by providingI the bowl with a tan or spreader located at and over the water-inlet el' the bowl.

Thedischarge-passage D of an earthenware water-closet bowl has a flange N,-wl1ich is integral with it and which makes one part ol the connection for bowl with the metal wastepipe G in continuation of the discharge D.

O is a metal flange or ring surrounding and suitably attached, as well known, to the waste-pipe G and opposite to the under face of the bowl-flange N, and between thc two llanges is a packing l), oi' putty or other such like material. The waste-pipe G is entered into the discharge-passage D, which is of larger diameter than the external diameter of the pipe, so as to leave an annular space Q between the two and about the waste-pipe. This space Q at its upper end is open to the water-way of the passage D and at its lower end it is closed bythe packing P between the llanges N O.

The space Q between the waste-pipe G and discharge-passage D ot' the bowl and within the latter forms a receptacle for the deposit and constant retention of water, whereby the packed joint between the flanges of the waste-pipe and bowl is water-sealed and the escape of obnoxious gases thereat thus prevented..

The connection of waste-pipe G with the discharge-passage D ot bowl and ot the flange Nef bowl and metal flange O, all as described, constitute no part of this invention, but form the subject-matter of separate application for Letters Patent of the United States, Serial No. 308,183.

l IIa-ving thus described my invention, what l l claim, and desire to secure by Letters Pat` eut of the United States, is

l. The combination, with a water-eloset bowl adapted to be flushed and having two water-traps with a column of air between located in the discharge-passage of the bowl and making a siphon, a single water-supply pipe leading to the flushing means ot' the bowl, and an opening and closing valve to open and close said water-pipe, ot' two separate water Vways or passages leading from and both always inopen communication with said water-pipe, and one in communication with the flushing means of the bowl and the other directly with the air-column between the water-traps and ot an area less than the area of the water-pipe, whereby with said valve opened the water from the water-pipe is delivered simultaneously through one of said water-ways to the llnshin g means and through the other of said water-ways te the aireol umn between the water-traps, and with said valve closed sulistantially only to the flushing means, substantially as and l'or the pur poses described.

2. 'lhe eombinat ion, with a watercloset bowl adapted to be lushed'and having two water-traps with a column ot' air between located in the discharge-passage of the bowl and -making a siphon, a single water-suppl y pipe leading to the llushing means et' the bowl, and an opening and closingl valve to open and close said water-pipe, ot' two separate water ways or passages L M, leading Afrom and both always in open com m nnieation with said wateepipe, and one L in comm unication with the ilushing means ot the bowl andthe other M directly with the air-column between the water-traps, and having a projection ot' its walls a into and across the water-way L, whereby with said valve opened the water from the water-pipe is delivered simultaneously through one L of said water-ways tothe flushing means, and through the other M ot' said water-ways to the air-column between the water-traps, and with said valve closed substantially to the tlushing means, substantially as described, and for the purposes specilied.

In testimony whereof I have hereunto set my hand in the presence ot' two subscribing witrnesses.
